i386 to dev/acpi_support. In theory, these devices could be found
other than in i386 machines only as amd64 becomes more popular. These
drivers don't appear to do anything i386 specific, so move them to
dev/acpi_support. Move config lines to files so that those
architectures that don't support kernel modules can build them into
the kernel. At the same time, rename acpi_snc to acpi_sony to follow
the lead of all the other specialty devices.

about this driver, he suggested I commit it.

on UltraSPARC workstations. The driver is based on OpenBSD's SBus
cs4231 driver and heavily modified to incorporate into sound(4)
infrastructure. Due to the lack of APCDMA documentation, the DMA
code of SBus cs4231 came from OpenBSD's driver.
The driver runs without Giant lock and supports both SBus and EBus
based CS4231 audio controller. Special thanks to marius for providing
feedbacks during the driver writing. His feedback made it possible
to write hiccup free playback code under high system loads.

problem I had but it's happening in code that is messing around with
register windows - I'm willing to live with that piece being sensitive
to this and it looks like the other problems we had reported lately
are not fixed by using -O instead of -O2.
Sorry for the churn. Looks like I need a second pointy hat. Someone
tells me they stack well. :-))))
-O2 on kernel compiles after all. While working on adding a KASSERT
to sparc64/sparc64/rwindow.c I found that it was "position sensitive",
putting it above a call to flushw() instead of below caused corruption
of processes on the system. jake and jhb have both confirmed there is
no obvious explanation for that. The exact same kernel code does not
have the process corruption problem if compiled with -O instead of -O2.
There have been signs of similar issues floated on the sparc64@ mailing
list, lets see if this helps make them go away.
Note this isn't an optimal fix as far as the file format goes, if this
disgusts too many people I'll fix it the right way. Since compiling
with something other than -O is a known problem this format would prevent
a change to the default causing grief. And this may also help motivate
finding out what the compiler is doing wrong so we can shift back to
using -O2. :-)
My turn for the pointy hat... One of the florescent ones...

Allocation is always lowest free unit number.
A mixed range/bitmap strategy for maximum memory efficiency. In
the typical case where no unit numbers are freed total memory usage
is 56 bytes on i386.
malloc is called M_WAITOK but no locking is provided (yet). A bit of
experience will be necessary to determine the best strategy. Hopefully
a "caller provides locking" strategy can be maintained, but that may
require use of M_NOWAIT allocation and failure handling.
A userland test driver is included.
because it was mostly irrelevant - except for the silly BIOS_PADDRTOVADDR
etc macros. Along the way of working around this, I missed a few things.
* Make syscons properly inherit the bios capslock/shiftlock/etc state like
i386 does. Note that we cannot inherit the bios key repeat rate because
that requires a bios call (which is impossible for us).
* Give syscons the ability to beep on amd64. Oops.
While here, make bios.c compile and add it to files.amd64.

Users should move to the new geom_vinum implementation instead.
The refcount logic which is being added to devices to enable safe module
unloading and the buf/vm work also in progress would require a major rework
of the (old)-vinum code to comply with the new semantics.
The actual source files will not be removed until I have coordinated with
the geomvinum people if they need any bits repo-copied etc.
This is necessary so source upgrades use the correct binary.

For the record: Problem spotted by Scott Long, who mentioned
that source upgrades from 4.7 to recent 5.x and 6.0 are broken.
Detailed analysis shows that 4.7 has a broken make(1) binary.
A breakage was fixed in RELENG_4 in make/main.c,v 1.35.2.7 by
imp@, though the commit log erroneously stated "MFC 1.68"
while in fact it should have been spelled as "MFC 1.67".
